## College Algebra (10th Edition)

In order to verify that they are both solutions, we substitute the values of both variables into both equations to ensure that they produce a true result: $$3(2) - 4(.5) =4 \\ 4=4$$ For equation two: $$.5(2)-3(.5) = -.5 \\ -.5=-.5$$ Both equations are true, so the solution is correct.
